Unsure what this insect is but it looks similar to a Lacewing nymph except for having two sets of pincers. The insect was initially sighted on one of the right legs of the emerging Boisduval's Autumn moth before moving round on the wall to approach the moth's head. It then moved around on the wall and approached the left side of the moth (final three images) before climbing onto the moth and then disappearing beneath it. There was no reaction from the moth. Thanks to Marcus Leach for help with this sighting.
